Lags, artefacts and LOW fps in game if i open youtube or anything in full screen in another monitor

Lags, artifacts and LOW fps in game if I open youtube or anything in full screen in another monitor. Two monitors full HD 1 60HZ and Primary 75. I tried changing the refresh rate, but it made no difference.
